GAS-GENERATOR.

Specification of Letters Patent.

To all whmn it may concern.-

Be it known that I, HENRY A. HARTMAN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Gas-Generator, of which the following is a specification.

My invention consists of a gas-generator having a retort of novel construction whereby fuel may be readily directed through the main body of the same by its own gravity Without necessarily requiring means to occasion said passage, while also providing means for preventing clogging of the fuel and coke in the retort, while the latter presents a large surface to the action of the heat of the furnace.

Figure 1 represents a partial elevation and partial vertical section of a gas-generator embodying my invention. Fig. 2 represents an end elevation thereof. Fig. 3 represents a Vertical section of a portion on line :0 .r, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a retort which is elbow-shaped and has one limb B opening into the water-column C, said column being mounted on the supports D and constituting a hopper.

E designates a furnace over which the limb or main body F oi the retort A is supported, said limb thus being adapted to be subjected to the heat of said furnace. On the end of the limb F opposite to the limb B is a downwardlydeflected limb G, which forms a continuity of the limb F and opens into the tank H, which is properly supported and adapted to receive water or other fluid, it being noticed that the retort A is of conical form, so as to increase in diameter in the direction from its inlet at the column 0 to its discharge or outlet at the tank H.

lVithin the limb B is a spiral conveyer J,

which is partly continued into the column.

C, the shaft of said conveyer having connected with it the pulley K, to which power may be communicated in any suitable manner, so as to rotate said conveyer.

Rising from the retort A are the pipes L, which are in communication with the same and with the main M, the latter being supported in any suitable manner above the furnace.

The operation is as follows: Coal is introduced into the column 0, and consequently made wet by the Water therein. As the conveyer J rotates the coal in wet condition is raised by the same into the limb B- and forced into the main limb F, where it is subjected to the heating action of the furnace, and thus coal-gas will result. At the same time as more coal reaches the upper portion of the limb F the Water therefrom Will pass down the limb F and be converted into steam, which must pass through the hot coal in order to reach the take-off pipes L, thus adding a percentage of gas to the larger quantity of coal gas made. The coke resulting from the treatment of the coal will be directed from the limb F into the limb G, from which it will be dropped into the tank H and cooled by the water therein,

after which it may be discharged from said tank in any suitable manner.

It will be noticed that owing to the conical or widening shape of the retort the coal successively entering the limbs B and F will be prevented from clogging therein, and so will discharge therefrom in a reliable manner, the coke formed in the limb F also being prevented from clogging therein as Well as in the limb G.

Various changes may be made in the details of construction shown Without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in this case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a gas-generator, a retort having a body and a supply-limb at an angle thereto, the said body and limb being inclined downwardly in opposite directions from their supply to their discharge ends and said body portion and limb increasing in diameter from the inlet to the discharge ends thereof.

2. In a gas-generator, a retort having a body and a supply-limb at an angle thereto, the said body and limb being inclined downwardly in opposite directions from their supply to their discharge ends and said body portion and limb increasing in diameter from the inlet to the discharge ends thereof and a downwardly-extended limb at the larger end of the body.

3. In a gas-generator, a retort increasing in diameter from its inlet to its discharge end and consisting of a body having a downwardly deflected supply limb at one end thereof' and a downward1yeXtending discharge-limb at the other end thereof, a water-receiving hopper and a Water-receiving tank, the supply-limb entering said waterreceiving hopper and the dischargedimb entering the water-receiving hopper and an elevator in said supply-limb.

4. In a gas-generator, a retort increasing in diameter from its inlet to its discharge end, a furnace below the body portion of said retort, a supply-limb at one end of said body, a discharge-limb at the other end thereof, an elevator in said supply-limb, a water-receiving hopper with which said supply-limb is in communication and a Water-receiving 15 tank into which dips said discharge-limb.

5. In a gas-generator, a retort of elbow form, of gradually-increasing diameter, means for supporting the same in inclined position, a supply-limb at the inlet end. thereof, an 20 elevator in said supplydimb and a hopper in communication with said supply-limb, said elevator partly entering said hopper.
